Patent CA-2086301-A1 (CA)
Inventor: BLACKLAW ROCKY A
IPC: B60D1/07
Filed: 1992-12-24
Abstract: A trailer coupling has a removable unitary coupler-receiving element that includes both a ball configured to receive a spherical cavity coupler and a cylindrical neck configured to receive a drawbar eye.  A latch is movable about a vertical axis between a closed position, where it engages the coupler-receiving element, and prevents removal of the eye from the neck, and an open position where it is separated from the coupler-receiving element and permits use of the ball.  A locking mechanism locks the latch in its closed position and holds it against free movement from its open position.  A trigger located in a finger-receiving cavity in the latch releases the locking mechanism.  Because the latch rotates about a vertical axis, it can have a low profile and not extend substantially above the ball in the orientation.

Title: Data recording and reproducing apparatus
Inventor: KOJIMA KUNIO
IPC: G11B27/10
Filed: 1993-01-22
Abstract: A data recording and reproducing apparatus uses a rewriteable optical disk with pre-recorded absolute address information, and comprises a data compression circuit for dividing  and  compressing  continuous  digital  data  into compressed plural data blocks, an expansion circuit to restore the compressed data to the original expanded form, and a buffer memory.  Data is compressed in discrete data blocks and is recorded sequentially block by block to the optical disk.          The compressed data is likewise read block by block from the disk during data reproduction.   Using the data expansion circuit to expand the compressed data one block at a time, the data recording and reproducing apparatus can reproduce the original continuous digital data stream.  Plural continuous digital data selections can thus be reproduced by alternately fetching data for the plural selections from the disk in compressed data block units and temporarily storing the data to a buffer memory for expansion.

Title: Method and device for the biological control of insects
Inventor: GUNNER HAIM B
IPC: A01N63/30
Filed: 1990-09-14
Abstract: A method for control and extermination of insects, including roaches, flying insects such as the housefly, and other insects such as the adult form of the corn rootworm by infection of the insects with a fungus that can be pathogenic when administered to the insects in a sufficiently high concentration, by means of an infection chamber. The chamber maintains the spores of a fungus pathogenic to the insects in a viable form, protecting the fungi from the environment (including rain, ultraviolet light and the wind), serves as an attractant for the insects, and serves to inoculate the insects with high numbers of spores. Although the primary means of infection is by external contact, the insects may also be infected by contact with each other and by ingestion of the spores. The two most preferred entomopathogenic fungi are Metarhizium anisopliae and Beauveria bassiana, although other fungi can be used which are pathogenic when the insect is inoculated via the infection chamber. Examples demonstrate control of Blattella germanica (the German cockroach), Periplaneta americana (the American cockroach), Fannia canicularis (little housefly), Musca domestica (housefly), and Diabrotica undecempunctata) using chambers containing Metarhizium anisopliae and Beauveria bassiana.

Title: Horse driven hitch cart
Inventor: TAYLER BARON
IPC: B62C5/00
Filed: 1991-12-16
Abstract: A horse-drawn hitch cart (10) has its tongue (60) adjustably positioned laterally, by means of a clevis (61) and plural hand-actuable locking pins (68), along an apertured drawbar (53) suspended forwardly and below the floor level of the cart frame to be rotatable about a laterally-extending axis. A yoke bar (89) is attached to the distal end of the tongue (60) by means of a yoke ring (91) circumscribing the tongue between two longitudinally spaced and hand-actuable stop pins (86, 88) preventing the ring (91) from being disengaged from the tongue. The proximal stop pin (88) position is adjustable to accommodate different length horses by virtue of a series of through holes (87) defined along the tongue rearwardly of the most distal stop pin. A clutch assembly (36, 37), actuable from the cart floor by means of a lever (35), permits a ground driven power takeoff unit (28) to be selectively engaged quickly and easily without requiring the driver to leave his seat.  A bias spring (46) and a mechanical stop acting (48) on the lever prevent inadvertent engagement and disengagement, respectively, ofthe clutch. Selective lateral positioning of a towed implement is made possible with a three-point hitch unit modified to permit rotation between the drive arms and the sidelinks about respective axes disposed in vertical planes.
Patent CA-2098288-A1 (CA)
Title: Distillation apparatus
Inventor: KOISTINEN PETER
IPC: B01D1/28
Filed: 1991-12-16
Abstract: The invention relates to a distillation apparatus (1) which is suitable in particular for the distillation of sea water into fresh water. The apparatus comprises a plurality of flat, bag-like elements (3) formed from a thin film material such as plastic film and placed one against the other, the elements serving as heat exchangers between a vaporizing liquid flowing along the exterior surfaces of the element and a condensing vapor directed to the inside of the element, and a compressor (15) for increasing the pressure and temperature of the generated vapor before it is directed to the inside of the elements.  The essential idea of the invention is that at the upper end of each bag-like element (3) there is a honeycomb-structured end strip (A) having substantially the width of the element, the strip containing parallel feeding ducts (26) separated from each other by partition walls, the ducts distributing the liquid to be evaporated over the entire width of the element surface. In addition, the strip (4) may contain ducts (25), formed in the same manner, which direct the vapor to be condensed to the inside of the element over the entire width of its end. At the lower end of the element there may additionally be a honeycomb-structured end strip (7), the ducts contained therein collecting the produced distillate into a collection vessel (8) and discharging any unvaporized liquid into a collection basin (9).

Title: Selective inhibition of leukemic cell proliferation by bcr-abl antisense oligonucleotides
Inventor: CALABRETTA BRUNO
IPC: A61K38/00
Filed: 1992-06-15
Abstract: Leukemias characterized by the presence of the Philadelphia chromosome and the expression of the hybrid bcr-abl gene are treated with antisense oligonucleotides complementary to a target sequence of the bcr-abl mRNA transcript including the breakpoint junction. Individual chronic myelogoneous leukemia patients or Philadelphia chromosome-positive acute lymphocytic leukemia patients are treated by first sequencing the individual's bcr-abl breakpoint junction, and then administering antisense oligonucleotides complementary thereto. The oligonucleotides are designed to hybridize specifically to the bcr-abl breakpoint junction without substantial cross hybridization to untranslocated c-abl sequences. Treatment may comprise in vivo administration of antisense oligonucleotides, or ex vivo treatment such as bone marrow purging.
Patent CA-2105361-A1 (CA)
Inventor: DONAHUE RAYMOND J
IPC: B22C9/04
Filed: 1993-09-01
Abstract: A method of producing a metal casting utilizing an expendable polymeric foam pattern along with unbonded sand having specific thermal properties. The pattern, formed of a material such as polystyrene, has a configuration corresponding to that of the article to be cast. The pattern is placed with an outer flask and unbonded sand surrounds the pattern as well as filling the cavities in the pattern. The sand has a linear expansion of less than 1% from 0°C to 1600°C, a particle size of 0.001 inch to 0.015 inch, and a heat diffusivity greater than 1500 J/m2/°K/s1/2. A molten metal, such as a hypoeutectic or hypereutectic aluminum silicon alloy or a ferrous alloy, is fed into the mold in contact with the pattern causing the pattern to vaporize with the vapor being entrapped within the interstices of the sand while the molten metal fills the space initially occupied by the foam pattern to produce a cast article. The physical properties of the sand enable articles to be cast having more precise tolerances.
